![]() Most VPNs, including Surfshark and CyberGhost, let you choose OpenVPN(UDP) and Open (TCP) to establish a connection. ![]() OpenVPN does not have native support but can easily be used by installing client software. Setting up IPSec protocols can be pretty complicated, but these days, the protocol is more commonly used via the IKEv2 protocol on third-party VPN apps. Instead, users can import configuration files to their servers and implement it. This means that you don’t need a third-party application to install and use this protocol. Most operating systems, including Windows, macOS, Android, and iOS, have native support for IPSec. Now that we’ve gone through the common VPN protocols, let’s take a closer look at the two most popular options - IPSec and OpenVPN - to understand how they differ and when you should use each. The only downside is that IKEv2 is exclusively available on UDP ports, which some firewalls can block. Top-notch VPN providers like Surfshark use IKEv2 due to the protocol’s significant strengths. As a result, it’s an excellent protocol for mobile devices across all platforms. It’s one of the newest protocols and is secure, fast, lightweight, and stable. Internet Key Exchange version 2 (IKEv2) is also part of the IPSec protocol suite and is a widely used VPN protocol. It’s easy to set up on most operating systems and provides excellent connection speeds.Įssentially, L2TP offers speed, while IPSec keeps your data secure via encryption. In most VPNs, IPSec is used in conjunction with L2TP (Layer 2 Tunneling Protocol). IPSec is used in many applications at the Internet Layer of the Internet Protocol Suite. It encrypts each individual IP packet in a particular communication. IPSec is a flexible protocol that is focused on the authentication and encryption of data. It has since become the standard protocol for securing online communication over an IP network. IPSec, or Internet Protocol Security, was developed by the Internet Engineering Task Force (IETF) in the 1990s.
